Elizabeth Warren has been projected as the winner of her Massachusetts Senate race, beating incumbent Republican Scott Brown and the many millions of dollars that banks and bankers spent to defeat her.

Warren has been an outspoken critic of the banking industry and a proponent of tougher regulation, and that industry fears she will carry that criticism to the Senate. Warren dreamed up, helped establish and temporarily ran the Consumer Financial Protection Bureau, the post-crisis watchdog for customers of banks and other financial services.
